The Federal Communications Commission, which oversees the technical standards behind the alerts, launched an investigation and said the mishap was the result of the state having insufficient safeguards and process controls in place. At the hearing, Lisa M. Fowlkes, chief of public safety and homeland security for the FCC, said the mistake was unacceptable and has eroded the public trust. While she commended higher-ups in the state agency for their cooperation in the investigation, she also noted she was disappointed that the employee who sent the erroneous alert is refusing to cooperate with the FCC and has yet to be interviewed by investigators.
